Researchers identify drug target for ATRA, the first precision cancer therapy

Cancerous tumors have the ability to evade targeted therapies by activating alternative pathways. Tumors also contain cancer stem cells, believed responsible for metastasis and drug resistance. Now scientists have identified a drug target that addresses both of these challenges.

Cisplatin is a first-line chemotherapeutic agent in non-small cell lung cancer (NSCLC), but the therapeutic effect is unsatisfactory, partly due to drug resistance.

Abstract Long non-coding RNAs (lncRNAs) have been identified to exert crucial roles in tumorigenesis and can serve as novel biomarkers for cancer therapy including lung cancer. Cisplatin is a first-line chemotherapeutic agent in non-small cell lung cancer (NSCLC), but the therapeutic effect is unsatisfactory, partly due to drug resistance. Emerging evidence showed that chemo-resistance is associated with acquisition of cancer stem cell (CSC)-like properties. Cisplatin resistance remains a major obstacle in the treatment of lung cancer, and its mechanism is still not fully elucidated. Meanwhile, CSCs have been invo...

Abstract It is a near-to-impossible not to accept that cancer takes position as the main cause of global burden of disease, for it is hard to ignore the outnumbered people dying from cancer. Looking at the statistics proves that progress in cancer therapy is always beyond cancer in a race of pessimism about the future; for various kinds of cancers yearly cause death in the world, whereas the conventional and even modern therapies often exhibit lack of reliability in treatment of cancer. In principal, various reasons are identified for cancer resistance and recurrence. Recognizing the cells/tissue from which cancer...

AbstractBoth miR675 and pyruvate kinase M2 (PKM2) contribute to malignant progression of tumor, but its functions in liver cancer stem cells remain unclear. Herein, our findings indicate that miR675 plus PKM2 strongly promotes the growth of liver cancer stem cells. Mechanistically, miR675 plus PKM2 enhances the transcriptional activity of SUV39h2. On the other hand, the excessive SUV39h2 binds to more substrate histone H3, triggering an increase of tri-methylation of histone H3 on the ninth lysine. Furthermore, the tri-methylation of histone 3 on the ninth lysine (H3K9me3)-heterochromatin protein 1 alpha (HP1 α) comp...

I'm pleased to note that the Methuselah Fund has closed its first fundraising effort after hitting the target amount, obtaining the support of many long-standing members of our community. The fund is a mixed for-profit/non-profit vehicle that is intended to expand the investment efforts undertaken by the Methuselah Foundation in past years, helping promising lines of rejuvenation research to make the leap from laboratory to commercial development. At the present point in time there are few enough rejuvenation focused companies that doing this well requires extensive connections within the research community, and a willingn...

UCLA researchers have discovered  genetic similarities between the adult stem cells responsible for maintaining and repairing epithelial tissues — which line all of the organs and cavities inside the body — and the cells that drive aggressive epithelial cancers. Their findings could bring about a better understanding of how ag gressive, treatment-resistant cancers develop and progress, and could eventually lead to new drugs for a range of advanced epithelial cancers such as lung, prostate and bladder cancers. The study, led by senior authors Owen Witte and Thomas Graeber, both of the  UCLA E...

Abstract Biomedical engineering seeks to enhance the quality of life by developing advanced materials and technologies. Chitosan-based biomaterials have attracted significant attention because of having unique chemical structures with desired biocompatibility and biodegradability, which play different roles in membranes, sponges and scaffolds, along with bring about promising biological properties such as biocompatibility, biodegradability and non-toxicity. Therefore, chitosan derivatives have been widely used in a vast variety of uses, chiefly pharmaceuticals and biomedical engineering. It is attempted here to dr...

DiPaolaAbstractProstate cancer is the most prevalent type of cancer in men. The etiology of prostate cancer development and the mechanisms underlying androgen-independent progression remains to be further investigated. There are many known targets for prostate cancer therapy including the androgen receptor (AR) axis, but resistance eventually develops in advanced disease suggesting the need to better understand mechanism...
